After several attempts to program the PE data to the mount via the iOptron ASCOM driver and thanks to the help of Ray Gralak, I have managed to do so. PEMPro has now reduced the periodic error from over 30 arc secs peak to peak to 6 arc secs peak to peak. If amyone is interested in viewing the PE curves/data, you can do so at the following link.
